Broadcast Power Control System for Parallel Element Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in efficiently managing and allocating electric power resources across multiple elements with varying priorities while adhering to total resource constraints, leading to increased communications traffic and difficulty in high-speed control, especially in large domains.
Innovation Solution
The implementation of a broadcast transmission system that measures differences in total consumed electric power, determines indication values for adjustment, and transmits these values to all elements within a domain, allowing each element to independently update its power consumption based on its priority, reducing the need for one-to-one communication with a server and minimizing communications traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a server centrally manages and allocates electric power to each element individually, then power allocation precision is improved, but communications traffic increases and control speed decreases
Solution Approach 1:
The patent divides the centralized power management function into two parts: the server calculates global power allocation based on total consumed power and priority weights, then broadcasts only the necessary adjustment indication to all elements. Each element independently adjusts its own power consumption. This segmentation reduces communications traffic while maintaining allocation precision.
Solution Approach 2:
The patent transitions from a one-to-one communication model (server to each element individually) to a one-to-many broadcast model. The server broadcasts a single indication value representing total power adjustment needed, and all elements receive this simultaneously. This dimensional change in communication architecture reduces traffic while enabling parallel processing at the element level.
2Measurement precision
If one-to-one communication is used between server and each element for power updates, then control precision is improved, but communications traffic increases significantly in large domains
Solution Approach 1:
The patent merges the individual control messages into a single aggregated indication value that represents the total power adjustment needed across all elements. Instead of sending separate messages to each element, the server combines all allocation decisions into one broadcast message containing the indication of total consumed power to be adjusted, reducing communications traffic while preserving control precision.
3Measurement precision
If centralized calculation of power allocation is performed by the server, then allocation accuracy is improved, but system complexity and communication requirements increase
Solution Approach 1:
The patent extracts the complex individual allocation calculations from the server and replaces them with a simpler broadcast mechanism. The server only needs to calculate the total indication value based on priority weights and power constraints, then broadcast this single value. The complexity of individual element calculations is eliminated, as each element uses the same indication value with its own priority weight to determine its adjustment.
4Measurement precision
If elements update their power consumption sequentially based on server instructions, then control accuracy is maintained, but processing time increases
Solution Approach 1:
The patent implements periodic broadcast cycles where the server periodically calculates and broadcasts the total power adjustment indication, and all elements simultaneously update their power consumption in each period. This periodic synchronized action enables parallel processing while maintaining control accuracy through regular feedback cycles.
Solution Approach 2:
The system uses feedback where elements monitor their own power consumption and the broadcast indication value, then adjust accordingly. Each element compares the received indication with its current consumption and priority weight, and autonomously adjusts to achieve the target allocation. This feedback mechanism maintains accuracy while enabling distributed parallel processing.

AI summary
It is a problem to be solved to provide Electric power control systems and methods which do not require one-to-one communications in both directions, in which the communications traffic does not rapidly increase even if the number of electric power consumption elements increases and which have good expandability. In addition, it is also a problem to be solved to provide information transfer capability control systems and methods which can be worked by the similar principles. In over to solve the problems, information representing an indication value for adjusting total consumed electric power which is a function of the difference between a current value and a reference value of the total consumed electric power in the group is transmitted by broadcast. Respective electric power consumed elements included in the group receive the information, and calculate, independently and in parallel, their own update values for consumed electric power by an operation using their own degrees of priorities and the indication value for adjusting total consumed electric power, and control their own consumed electric powers based on this. Information transfer capabilities can be controlled by the similar principle.
